Inzlingen is located in the district of Lörrach, Baden-Württemberg, in the very south-west of Germany just at the Swiss border line near Basel.

The first written evidence dated 1511[1] – at this time already a possession of a relative of the barons Reich von Reichenstein.

This noble family hold fiefdoms from the Prince-Bishopric of Basel, the Margraviate of Baden and the House of Habsburg.

Since 1820 the castle was a domicile for a weaving mill producing silk ribbons and afterwards it was used for a century as a farm house.

In 1980 the Deutsche Post issued a stamp showing an engraving of Inzlingen castle.
